Answer: OPTION C.
Step-by-step explanation:
The area of a triangle can be calculated with the following formula:
Where "b" is the base of the triangle and "h" is the height of the triangle.
You know that all the triangles that compose the large triangle are equal.
According to the information given in the exercise, the base and the height of any small triangle are:
Therefore, the area of any of them is:
Since there are 4 equal triangles, you need to multiply the area obtained by 4 in order to find the area of the large triangle. This is:
44 because if you use the equation y=mx+b you would plug in 5.8(5)+15 which equals 44
Answer:
Step-by-step explanation:
Given that:
The numbers of the possible public swimming pools are 5
From past results, we have 0.007 probability of finding bacteria in a public swimming area.
In the public swimming pool, the probability of not finding bacteria = 1 - 0.007
= 0.993
Thus;
Probability of combined = Probability that at least one public
sample with bacteria swimming area have bacteria
Probability of combined sample with bacteria = 1 - P(none out of 5 has
bacteria)
Probability of combined sample with bacteria = 1 - (0.993)⁵
= 1 - 0.9655
= 0.0345
Thus, the probability that the combined sample from five public swimming areas will show the presence of bacteria is 0.0345
From above, the probability that the combined sample shows the presence of bacteria is 0.0345 which is lesser than 0.05.
Thus, we can conclude that; Yes, the probability is low enough that there is a need for further testing.
